The Validation of a Human Force Model to Predict Dynamic Forces Resulting from Multi-Joint Motions by National Aeronautics and Space Administration (NASA) Pdf

The development and validation is examined of a dynamic strength model for humans. This model is based on empirical data. The shoulder, elbow, and wrist joints were characterized in terms of maximum isolated torque, or position and velocity, in all rotational planes. This data was reduced by a least squares regression technique into a table of single variable second degree polynomial equations determining torque as a function of position and velocity. The isolated joint torque equations were then used to compute forces resulting from a composite motion, in this case, a ratchet wrench push and pull operation. A comparison of the predicted results of the model with the actual measured values for the composite motion indicates that forces derived from a composite motion of joints (ratcheting) can be predicted from isolated joint measures. Calculated T values comparing model versus measured values for 14 subjects were well within the statistically acceptable limits and regression analysis revealed coefficient of variation between actual and measured to be within 0.72 and 0.80.

Computer Methods in Biomechanics and Biomedical Engineering 2 by J. Middleton,Gyan Pande,M. L. Jones Pdf

Contains papers presented at the Third International Symposium on Computer Methods in Biomechanics and Biomedical Engineering (1997), which provide evidence that computer-based models, and in particular numerical methods, are becoming essential tools for the solution of many problems encountered in the field of biomedical engineering. The range of subject areas presented include the modeling of hip and knee joint replacements, assessment of fatigue damage in cemented hip prostheses, nonlinear analysis of hard and soft tissue, methods for the simulation of bone adaptation, bone reconstruction using implants, and computational techniques to model human impact. Computer Methods in Biomechanics and Biomedical Engineering also details the application of numerical techniques applied to orthodontic treatment together with introducing new methods for modeling and assessing the behavior of dental implants, adhesives, and restorations.

Computer Animation and Simulation 2000 by N. Magnenat-Thalmann,D. Thalmann,B. Arnaldi Pdf

This volume contains the research papers presented at the Eleventh Eurographics Workshop on Computer Animation and Simulation which took place in Interlaken, Switzerland, August 21-22, 2000. The workshop is an international forum for research in human animation, physically-based modeling, motion control, animation systems, and other key aspects of animation and simulation. The call for papers required submission of the full papers for review, and each paper was reviewed by at least 3 members of the international program committee and additional reviewers. Based on the reviews, 14 papers were accepted and the authors were invited to submit a final version for the workshop. We wish to especially thank all reviewers for their time and effort in working within the rigid constraints of the tight schedule, thereby making it possible to publish this volume in time for the workshop. We also thank the authors for their contributions to the workshop, without whom this unique forum for animation and simulation work would not exist. We are grateful to the Eurographics Association and especially to Werner Purgathofer from the Technical University of Vienna, for his support in publishing the workshop as a volume of the Springer-Verlag Eurographics Series. We also thank the Eurographics '2000 organisers, especially David Duce, and Heinrich Miiller from the EG board. We are also very grateful to lerrin Celebi for the organization of the review process and and Josiane Bottarelli for the registration process.

Handbook of Virtual Humans by Nadia Magnenat-Thalmann,Daniel Thalmann Pdf

Virtual Humans are becoming more and more popular and used in many applications such as the entertainment industry (in both film and games) and medical applications. This comprehensive book covers all areas of this growing industry including face and body motion, body modelling, hair simulation, expressive speech simulation and facial communication, interaction with 3D objects, rendering skin and clothes and the standards for Virtual Humans. Written by a team of current and former researchers at MIRALab, University of Geneva or VRlab, EPFL, this book is the definitive guide to the area. Explains the concept of avatars and autonomous virtual actors and the main techniques to create and animate them (body and face). Presents the concepts of behavioural animation, crowd simulation, intercommunication between virtual humans, and interaction between real humans and autonomous virtual humans Addresses the advanced topics of hair representation and cloth animation with applications in fashion design Discusses the standards for Virtual Humans, such as MPEG-4 Face Animation and MPEG-4 Body Animation.
